Cystic hygroma (CH) is a congenital malformation of lymphatic system. The incidence of CH is approximately 1 in 6000 live births. In most of the cases, it presents as a painless, fluctuant swelling. Due to its variable presentation its optimum treatment often poses a potential challenge. Keywords: Cystic hygroma, lymphangioma, neck swelling

Introduction | | |
Cystic hygroma (CH) is a congenital entity which occurs due to failure in development of communication between lymphatic and venous system. The incidence of CH is approximately 1 in 6000 live births. [1] CH is considered as a developmental tumor of lymphatic origin and is a relatively rare lesion. [2] CH often presents as a swelling in head/neck region accounting for 70-80%, other sites includes mediastinum, axilla, pelvis. [3] Its treatment modalities comprise surgical excision, use of sclerosants, repeated aspiration, conservative management. We present a case of an 18-month-old male child with swelling around the left side of the face extending up to neck with a gradual progression and resulting in stridor and restricted mouth opening.
Case Report | | |
An 18-month-old male child weighing 8.8 kg presented to our hospital with swelling on the left side of face which had gradually increased with time for which patient was referred to a higher center. Swelling was minimal on the face at birth but had progressed considerably with time [Figure 1]. Initially injection bleomycin (intralesional) 0.5 mg/kg was administered. In spite of injection bleomycin, the lesion progressed further leading to stridor and restricted mouth opening. In course of time repeated aspiration was done under all aseptic conditions to improve patient symptomatically. Ultrasonography of neck region showed multilocular appearance with variable density with combination of fluid, soft tissue, and fat with cyst extending to anterior aspect of the neck. Magnetic resonance imaging (MRI) showed multiple cystic lesions within left masseter muscle and extending to anterior aspect of neck and into subcutaneous fat plane. Considering rapid increase in the size of the swelling and development of stridor patient was subjected for surgical procedure under general anesthesia [Figure 2]. Surgical enucleation was done, subplatysmal flaps were raised exposing the multicystic lesion [Figure 3]. Multiple cystic lesion was removed into preserving carotid vessels, jugular vessels, and spinal accessory nerve [Figure 4]. Histopathological findings were consistent with CH and patient was kept in Pediatric Intensive Care Unit for postoperative period. Postoperative period was uneventful. | Figure 1: Swelling extending from left side of face up to anterior aspect of neck

Discussion | | |
CH is lymphatic in origin which occurs due to sequestration or obstruction of lymphatic sacs. In more than 50% of cases, it presents at birth and in remaining cases it present by 2 years of age. However, in some extremely rare cases, CH has been reported in adulthood. [4]
CH is associated with various syndromes such as turner syndrome, Noonan syndrome, and fetal hydrops. [5] Around 70-80% of CH presents as a swelling in head/neck region however in some cases it can present at axilla, mediastinum, pelvis. [3] CH are classified as superficial CH (Lymphangioma circumscriptum) and deep ones (cavernous lymphangioma or cystic hygroma). [6]
Microscopically cyst wall consists of a single layer of flattened epithelium which may or may not contain vascular component, however, in some cases rapid enlargement/discoloration of the swelling can be attributed to the vascular component. [7] Characteristics of CH are fluctuant, brilliant transilluminant, and it never becomes malignant. [8] Diagnostic modalities to confirm the diagnosis of CH along with clinical suspicion includes ultrasonography (antenatal), computed tomography (CT) scan, MRI, which can give the exact extent of the lesion and regarding infiltration into adjoining structures. CT scan with contrast is better in localizing the lesion and its extent, but MRI is still considered better in localizing lesion due to its better accuracy and lack of artefacts. [9] Various treatment modalities have been considered for successful treatment of CH, which includes sclerosant agents, repeated aspiration, injection bleomycin, radiotherapy, surgical exploration. [10] Due to difficult and challenging surgical procedure owing to multicystic nature of the lesion with thin wall and proximity to vital neurovascular structures many nonsurgical options have been advocated which includes injection bleomycin administration intralesionally, a study by Oxfard et al. concluded that complete resolution had occurred in 44% cases and no response in 12% cases with use of bleomycin. [11] However, many authors have suggested the use of nonsurgical management in asymptomatic cases only, a study by Alqatein reported spontaneous regression is often associated with recurrence and hence is not valid treatment for CH and concluded that surgical excision of the lesion should be considered in all cases. [12]
Conclusion | | |
In developing countries like India where ignorance and lack of proper medical facilities at basic level prevails, cases of CH which are rare in occurrence and often report after considerable progression, therefore, their optimal treatment is delayed. Therefore, owing to the challenge posed by its variable and delayed presentation it becomes optimum to be rapid in diagnosing and treating a case of CH. Complete surgical excision should be considered treatment of choice in symptomatic cases, however, nonsurgical (conservative approach) can be tried initially for asymptomatic cases.
